Solar energy is the energy that comes from the light and heat from our sun and can be harnessed by different technologies.
The sun is a clean, free and limitless source of energy. The production of solar energy not only reduces gas emissions which contribute to climate change, but it is an excellent way to save money.
"The sun is an inexhaustible source of energy and, like all forms of renewable energy, solar energy is much more environmentally and climate-friendly than fossil fuels. The potential for electricity generation on Swiss roofs and facades is high, but it is far from being fully exploited, with only 5% of the usable surfaces being used.”
If we had more solar energy, what would that change for individuals?
Today, most individuals invest in solar energy and use it for their own consumption. However, they continue to purchase their residual power from local suppliers. These homes are called “prosumers”, which means that they are both producers and consumers of solar energy. This saves them the cost of electricity. With widespread use of solar energy, homes will be more independent.
In terms of the cost-efficiency ratio and the environmental footprint, how does solar energy compare to other renewables?
Within the current policy framework, and the declining costs of photovoltaics, solar energy is already a safe and environmentally responsible investment if the location of photovoltaic panels is chosen carefully. Of all the technologies currently available for electricity generation, photovoltaics is an attractive option for its environmental performance.
How do you see the future of solar energy in Switzerland?
Solar produced electricity will capture a significant share of the energy market, notably by replacing the nuclear share, and in the future, we will begin to harness solar power for regional electricity production. More and more direct consumer groups and prosumers will appear on the market. They will help balance individual consumption using storage solutions and shape more grid-related energy consumption, as they represent the most efficient, cost-effective and environmentally friendly approach. In addition, solar and hydraulic electricity will be increasingly used to recharge electric vehicles or to produce hydrogen as a buffer storage element.
